CVE-2026-23002

CVE-2026-23002 affects the Linux kernel’s buildid path. The fix switches the sleepable context reader to use __kernel_read() for reading file data instead of direct page cache access via read_cache_folio(), reducing the risk of a NULL pointer dereference in filemap_read_folio. The patch keeps exi...

CVE-2022-50430

CVE-2022-50430 affects the Linux kernel mmc vub300 driver. The fix prevents calling blocking operations when the current task is not TASK_RUNNING by ensuring vub300_enable_sdio_irq() uses proper mutex usage and marks the current task as TASK_RUNNING in a sleepable context. This reduces a potentia...

PT-2025-40115

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.1.0-rc5 Description The Linux kernel contained an issue within the vub300 driver related to handling interrupts in sleepable contexts. Specifically, the vub300 enable sdio irq function did not properly ensure...
